Abstract
A system is described for processing predicates in the course of analyzing a program, based on a general-purpose theory of pointers. The system converts location expressions in the predicates into logical formulae that are interpretable by a theorem prover module, producing converted predicates. This conversion associates the location expressions with location objects. More specifically, the conversion represents variables as explicitly-specified location objects, and location terms (such as a field-type access terms and dereference-type terms) as constructor-specified location objects. The theory of pointers is also expressed by a set of axioms which constrain the operation of the theorem prover module.
